CONVEYER THOUGH AND CHUTE.

Specification of Letters Patent.

Patented Aug. 29, 1905.

Appliaation filed November 27, 1903. Serial No. 182,805.

To all whmn it may concern.-

Be it known that we, GEORGE R. YOUNG, a resident of Ridgewood, county of Bergen, State of New Jersey, and FREDERIoK A. TE- TOR, a resident of West Pittston, county of Luzerne, Pennsylvania, citizens of the United States, have invented certain new and useful Improvements in Conveyer Troughs and Chutes, of which the following is a specification.

This invention relates to means for conveying and screening coal, minerals, and other material. Its object is the production of a trough and chute with perforations which will allow the separation of small particles from the main bulk of the material while being conveyed and also the separation of dust and the like from the said small particles.

In the drawings we have shown the invention applied to a coal-conveyer operating with a hopper extending below railway-tracks.

Figure 1 represents a section of Fig. 9. as on the line 02 Fig. 2 shows a partial section of Fig. 1 on the lines 00 m and 00 An ordinary railway-trestle is represented, with the posts A, cross-ties B, longitudinal stringers (1, bottom cross-pieces D, braces E, and tracks F. A receiving-hopper G is located between the posts A and has the sides 9 g and ends g 9 An opening g is formed in the side 9, from which extends a chute H. Fitted in the said chute is the door or gate 1, which swings on a pin 6 and has a handle J, which latter swings over a sector K, to which the said handle can be fastened by a pin 7r. At 0 there is shown an inclined trough, in the bottom of which are formed perforations O, forming a screen leading to a screeningbox P, which has an inclined bottom 9, with perforations 0 an outlet at p, and forms a second screen. Below the said screening-box P there is located a dust-chamber P, with an outlet Q.

In the bottom of the chute H are formed perforations 7t, forming a screen that leads to a screening-box R, in the bottom r of which are perforations h, forming a second screen, that leads to a dust-chamber R. The screening box R leads to and connects with the screeningbox P, and the dustchamber R leads to and connects with the chamber P. The perforations O, 0 7b, and 7b are preferably made countersunk at their bottom outinto the conveyer-trough 0.

let ends, as shown, although they may be made cylindrical.

In the trough 0 there is indicated a flight conveyer having the chain S, from which extend flights S, the said chain being shown with the sprocket-chain wheel S mounted on the shaft S the latter turning in journalboxes S, mounted on suitable framing A reservoir T extends below the trough 0.

To use the invention, coal or the material to be conveyed and screened is dropped from a car into the hopper Gr, from which it is allowed to run by lowering the door or gate I to the position shown in Fig. 2, and while the coal is running down the chute H the line and small particles will drop through the perforations lb, while the larger pieces will run The fine particles will be screened of their dust by means of the perforations h and will run into the screening-box P and from thence out of the outlet 1), while the dust will run from the said dust-chamber R to the dust-chamber P and will be deposited from the latter by means of the outlet Q. The large pieces of coal on leaving the chute H and falling into the trough O are acted upon by the conveyerflights S and by so doing are separated a second time from their smaller particles, which drop through the perforations O and which small particles run to the outlet 1), they being screened in so doing over the perforations 0 the dust collecting in the chamber P and being taken out at the outlet Q:

Having described our invention, we claim 1. The combination of a hopper having an opening at its lower end, a chute having perforations extending from said opening, a gate swinging from said opening in the hopper, a handle on the gate, a sector, means to secure the handle on the sector, ascreening-box having perforations below the chute, adust-chamber below the said box, an inclined trough below the chute and having perforations, a screening-box below the trough having perforations and connecting with the screeningbox below the chute, a dust-chamber below the screening-box of the trough and connecting with the dust-chamber of the chute, a flight conveyor operating in the trough, and a reservoir at one end of the trough.

2. The combination of a trestle, a hopper connected thereto having an opening at its lower end, a chute having countersunk perforations extending from said opening in the chute, a flight conveyer operating in the trough, and a reservoir at one end of the.

trough.
